Was it not undemocratic of this country not to have accepted the final total back in 2016 ?
For a start, EV, whether or not individuals accepted it is neither here nor there. The current government accepted it and tried to implement it.
However, it is the democratic right of people to oppose a decision they disagree with; it's even enshrined in our constitution as 'Her Majesty's loyal Opposition'.
It is also held that democracy involves 'free and fair' voting. The referendum fulfilled the first requirement 'free' but signally failed to fulfil the second, 'fair'. Blindly respecting the result of a corrupted process is not democratic in my, and thousands of others, eyes.
